Abstract

A coupled model of piston secondary motion and mixed hydrodynamic lubricated was established based on flexible multi-Body dynamics. The model included elastic deformation and roughness of the two surfaces. The effects of rough surface compared to absolutely smooth surface on piston secondary motion mixed lubrication are discussed. The results show that roughness of the surface can make the fluid a better way to lubricate the surface and decrease the secondary motion, but in the high load asperity contact will occur.
